and the current draw on our bike systems, here's an example for you.

and yes I know all amps are not created equal, even amongst the same manufacurers but..


This image was taken last night.
(2) Soundstream PN4.900D amps (1800 watts, 1200 in my configuration)

Ear bleeding volume level (ACDC - You Shook Me), all 4 gains set at exactly 12-oclock position.

 

Impressive. I'd like to see what GP's amps pull for comparison.

 

yeah that would be interesting to see but being alpine I would bet it notfar off from mine. I just got this meter a few days ago so I'll be testing different configurations as I install them for folks. Mostly what I do is a pair or maybe 2 of speakers and either the SS PN2.350D, SSPn4.520D, or the RF PBR300x2 depending on configuration and head units.

 

I have it's cousin (Precision Power 900.4) in my truck. Very impressive.

 

and with a battery (stock HD) that "supposedly" has 15ah to 50% battery capacity, that's a lot of sitting around drinking beer with a jukebox on 2 wheels... :-)

 

So for the non inteligent folks here ( me ), how long should we be able to run the stereo on accessory and still start the bike?

 

You betcha! So, what does your current setup look like? Have a thread here somewhere?

 

Believe it or not, it is directly related to the music you play, and ESPECIALLY how hard the bass hits.

I can get about a half an hour of 'play time' until I get nervous ! If you are pushing serious bass, it could be a little less, but bass is the BIG draw of power !!

 

not yet.. working on it though..

 

no doubt! but I don't listen to bass-blasting music so I'm good with what I see.

On the flip side of that I would think even with some good solid bass I wouldn't see anything higher than 8A. I'll try and play with it over the weekend and see.
